F. HIMMEL ET AL BUILDING MATERIAL Filed Feb. '7, 1929 rammed Dec. 31, 1929 UNITED STATES PATENT OFFICE FRED HIMMEL AND ISIDORE HIMMEL, OF NEW HAVEN, CONNECTICUT, ASSIGNORS TO THE HIMMEL BROTHERS CO., OF NEW HAVEN, CONNECTICUT, A CORPORATION BUILDING MATERIAL Application filed February 7, 1929. Serial N'o. 338,094.

This invention relates to improvements in building material and particularly to metal inishings for store-iront construction, pillars, and other places where a panel is arranged between two pieces of molding and especially when moldings are formed from extruded material and the panel from a strip oi' sheet-metal. In such construction it is desirable that the outer face of the panel at its edges should closely abut against the edge of the molding-strips, so that there will be no opening between them, and the object of this invention is to accomplish this result without the use of screws or other clamping device, and the invention consists in the con struction as hereinafter described and particularly recited in the claims.

In the accompanying drawings:

Fig. l is a sectional view showing two molding-strips with a panel-plate located between them; and

Fig. 2 is a perspective view of a section of the paneLplate detached.

In carrying out our invention we employ molding-strips5 preferably ot extruded material and formed in their adjacent sides with slots 6 and preferably the inner walls of the slots will beformed with shoulders 7. Between the two strips 5 a panel-plate .8, of sheet-metal, will be placed and this plate is formed in opposite sides with inwardly-ein tending V -shaped longitudinal bends to provide bearing-points 9 and this plate is inserted into the slots in the strips 5. In forming the strip romextruded metal, it is necessary that the slots shall be oi a certain width, and this width is greater than the thickness ot sheet-metal used for the panel-plates. If the shoulders 7 are employed, the space between the shoulder and the outer wall of the slots will approximately correspond to the thickness of the panel 8 and when inserted the bearings 9 rest against the inner walls of the slots, while the outer surface of kthe panels bear against the outer walls of the slots so as to form a tight joint between them.

In assembly one of the molding-strips is secured in place; the sheet-metal panel 8 is then inserted into the fixed strip; the other end inserted into the slot of the other moldingstlrip and the other molding-strip secured in p ace.

While the panel 8 will be formed from material of the required width, the slots permit oiI such variation between the strips as is reliable to occur in construction. The panel 8 is thus held in position and no open joint is formed between it and the molding-strips.

l/Vc claim:

l. Building material of the character de scribed, comprising a molding-strip formed in one side with a longitudinal slot combined with panel-plate thinner than the width of the slot and formed near one side with an inwardly-extending bend adapted to enter the slot in the molding-strip and contact with the rear wall of the slot, whereby the outer tace of the panel is held against the outer wall of the slot.

2. The combination with two moldingstrips formed in their adjacent faces with longitudinal slots and a panel-plate thinner than the width of the slot and formed near its edges with inwardly-extending V-shaped bends adapted to enter the slots in the molding-strips and contact with the rear walls of the slots, whereby the outer face of the panel is held against the outer walls of the slot.

3. The combination with a molding-strip formed in one side with a longitudinal slot, the inner4 wall of the slot provided with a shoulder combined with a panel-plate thinner than the width ot the slot and formed near one side with an inwardly extending bend adapted to enter the said slot and contact with the rear wall of the slot, whereby the outer face of the panel is held against the outer wall of the slot.

In testimony whereof, we have signed this specification.
